IPC: C08G69/00
Filed: 1982-08-05
Abstract: PURPOSE:To obtain the titled polymer, by subjecting an aminophenol or amino- alcohol and a benzene ring-containing dicarboxylic acid to polycondensation in the presence of a specific phosphorus compound, by the direct reaction of both the compounds. CONSTITUTION:An organic compound such as 4-aminophenol, ethanolamine, having an amino group and an alcoholic or phenolic hydroxyl group in the molecule and a dicarboxylic acid such as terephthalic acid, naphthalene-2,6-dicarboxylic acid, having a benzene ring in the molecule are subjected to polycondensation at 80-120 deg.C with stirring in the presence of a phosphorus compound such as diphenyl chlorophosphate shown by the formula (R<1> is aryl, alkyl, or aralkyl; X<1> is halogen).

Title: Thickness increasing press method for sheet metal
Inventor: ARINO SOICHI
IPC: B21K1/42
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide a thickness increasing press method for a sheet metal capable of forming a thick-walled part free of fold marks in part of the sheet metal only by the pressing without requiring machining. SOLUTION: The thick-walled part Wd is formed in part of the sheet metal through a preforming stage for forming a tapered flange part in part of the sheet metal blank by tapering or tapering process and a thickness increasing stage for crushing part of this tapered flange part in a direction where its thickness decreases, thereby fluidizing an excess metal (portion a) to required points (space parts b, c). The thick-walled part Wd is formed in part of the sheet metal by crushing part of the tapered flange in the direction where the thickness decreases and fluidizing the excess metal generated by the crushing within the range of the thickness of the sheet metal blank in the thickness increasing stage and, therefore, the generation of the fold marks in the thick- walled part Wd is averted and, consequently, the need for the machining to remove the fold marks is eliminated and the formation of the thick-walled part Wd free from the fold marks in part of the sheet metal only by the pressing is made possible. The man-hours for working may be decreased and the cost reduced.

IPC: F04C29/02
Filed: 1982-08-09
Abstract: PURPOSE:To increase the capacity and the coefficient of performance of a refrigerator, by providing an oil impregnating means on the side of a coolant inlet chamber in a cylinder, and thereby reducing the amount of leaked coolant gas. CONSTITUTION:Provided that the internal pressure of a suction chamber 15 is P1, the internal pressure of a compression chamber is P2 and pressure at the portion 10 of a lubricating oil groove opened in the cylinder is P3, the relationship between them is as follows; P3-P1>P3-P2. Thus, since the portion 10 of the lubricating oil groove opened in the cylinder is disposed on the side of the suction chamber 15, a high pressure difference is obtained. Therefore, a sufficient amount of lubricating oil can be supplied directly to a sealing portion 12 of a roller 2 located on the side of the suction chamber 15, and a positive sealing performance can be obtained, so that it is enabled to raise the refrigerating capacity and the coefficient of performance.

Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To eliminate types by fixing a kanji-mixed character string to be printed by a word processor function and printing the character string on a side face of a pencil by a printing means. SOLUTION: A kana character string which is inputted by a keyboard 4 and words which are sequentially converted by a conversion means are displayed at a display 5 by a display means of a character-setting mechanism part 1 having nearly the same mechanism as a general word processor.

Title: Automatic answering telephone set
Inventor: SHINDO AKIKO
IPC: H04M1/65
Filed: 1990-05-28
Abstract: PURPOSE:To improve the operability corresponding to the case when the user forgets a remote control command by allowing an automatic answering telephone set to discriminate a guidance command from an external telephone set and to send a remote control guidance. CONSTITUTION:When a password is entered from a telephone set at a visit place, the automatic answering telephone set is set to the remote control mode and a remote control guidance is listened to therefrom. When the remote control command to be stopped can not be grasped in the middle of message reproduc tion, the remote control command '*' is inputted, for example. The automatic answering telephone set deducts a remote control command to be executed next from its own execution state at present and sends the relevant remote control guidance. The similar operation is implemented even on the way of message reproduction. Thus, even when a remote control command table is not carried with the user and the user forgets the remote control command, the event is relieved and the operability is improved. Furthermore, since the remote control is able to be guided, the study effect is enhanced.
